repl: print errors in red

[avivkeller]

This change will have NodeJS REPLs print errors in red, so that they are easily distinguishable from traditional loggings. This change will not affect console.error

The tests failed due to them not prepared for the color scheme. I can change them once this PR is approved/reveiwed

I don't know what others think, but I personally think that it would be best to also change the tests.

The only issue with this (so far) is that when the user throws an object itself, the coloring get's reset after a change:

"\x1B[31mUncaught { foo: \x1B[32m'test'\x1B[39m }\x1B[39m\n"

Uncaught { foo: 'test' }

Imagine that Uncaught { foo: is red, and 'test' } is white

But, the user would have to directly throw an object within the REPL, which almost never happens

I'm not quite sure what went wrong here

[avivkeller]

I don't think I'll end up merging this PR, as I'm trying to merge nodejs/repl into the main NodeJS, which will redo all of this anyway.

See #52510 and nodejs/repl#54
